This research mainly adopts modified sol-gel preparation of nanometer level - glue of titanium catalysts, in light of the sol-gel preparation of titanium dioxide experiment using glacial acetic acid, gel process and n-buoh occur esterification reaction of water and butyl acetate titanate on hydrolysis reactions. Another ice acetic acid has chelates function, can reduce the high speed of alcohol salt, avoid fast hydrolysis of precipitation and the homogeneous tio2 sol-gel preparation. After drying, calcining sol-gel have nanometer tio2 power.
And through the load metal elements of Fe and nonmetal N on the surface modification, titanium catalysts to improve its catalytic activity, and the catalytic activity of XRD, DSC and TG/respectively/the characterization, select BET catalytic effect better photocatalytic materials for CO2 photocatalytic reduction reaction, CO2 into useful organic methanol, and theoretically explores CO2 photocatalytic reactions mechanism.
